NY Bill is right on target by allowing the weeds to grow tall, but in addition to his reasoning, I offer this information. Worms (specificically the "barber pole worm") generally do not travel farther than 4" up a stalk of grass. If you allow the grass to grow to 8" tall or taller, then as the deer graze on the tops of the grass and weeds, they are not exposed to the worm load they would get from shorter stems.
